Then he ordered the 16V 8A unit from us.

Yes, I remember watching his reviews of both models and that he bought one of them.

Some day I'll break down and get a Silent.
However, I have four of the little HP-6216A power supplies.  They were in my electronics lab in college and I instantly fell in love with them.  Only are 0.5 amp but you can parallel or series them together.

I have several of these as well, they are great for light duty bench work and can be found on eBay for $30-$50 if you wait a bit. Dead quiet, stackable and compact. I am working on an add-on digital volt & amp meter as the analog meter scales are a bit small fo my old eyes 😀
Hydron:
Can anyone confirm if the turn-on spike occurs with any meaningful load attached? Spike seems very short, so I'm wondering a) if it's even real and b) if it has any significant energy. I can live with the OCP/OVP being worthless - never really use these anyway, so this seems to be the biggest concern left.

Just a warning that from the videos I saw, it looks like the voltage at the output doesn't update immediately with turning the rotary encoder. Owners of the unit can confirm it's functionality, but that was enough to turn me off buying it.
GeorgeLouis:
Will this work in 120V 60Hz AC power line. Is there any way to change it's input voltage range.
